Abstract: The current disclosure relates to an apparatus and a process for producing poly-α-olefins (PAO), including reacting olefin monomers in a presence of a catalyst complex to form PAO product. The reaction is performed in a reaction including a reactor vessel and a system for recycling and cooling part of reactor outlet stream. At least one reactor is a cone reactor with a first cross sectional area in an upper part of the vessel and the cross sectional area decreases downwards to a second cross sectional area, which is smaller than the first cross sectional area.
